Hi Michael, Your first port of call might be the WCAG2 guidelines, found here; http://www.w3.org/WAI/GL/WCAG20/#media-equiv
I also did a quick search for "accessible online video best practice" and this link to a PDF from the US Department of Health and Human Services exactly on the topic of "Online Viral Video Requirements and Best Practices" might be useful to you. It is dated Jan 2010 and covers the departments use of YouTube (and other video providers) and importantly Section 508 compliance. A good deal of the document regards brand guidelines as much as technical requirements, but in that regards questions about dimension and file size and type might be useful knowledge. This was the PDF link; www.cdc.gov/socialmedia/Tools/guidelines/pdf/onlinevideo.pdf Accessibility advocate Joe Clark I recall became very interested in the question and quality of captioned video. >From my search above this resource of links from the Victorian Government in Australia might also be useful; http://www.egov.vic.gov.au/website-practice/online-video-content.html I'm not that knowledgeable about Flash, but to your questions I recall seeing a presentation from Adobe regards CS4 and that their Audio program, whose name escapes me, could extract Caption text and that in turn that file could be brought into Flash. However I thought it was an XML file. I also understood that using ActionScript you could program the import of the XML file, but the last time I used Flash was at school and it was Flash8 and given the presentation I mentioned it might be a tool built in?? Of course how this would be handled in HTML5 I'm less clear on:) Didn't really answer your questions directly, but I hope some of this is useful.
